ER-3700 UHF Dual Channel Wireless Microphone System

ER-3700 is designed for use on karaoke, bar, night club and high-end private clubs.Multi - functions, stable, easy to install product.

Key Features:

◆AFS (Automatic Frequency Selection):Press the "AFS"(Auto Frequency Selection) button 3 sec and the receiver will auto-scan and lock on to an open, interference-free

frequency.

◆IR Infrared:Press [IR] button to upload automatically the receiver frequency to the transmitter.

◆Anti-Interference:PLL (Phase Lock Loop frequency control) design ensures transmission reliability, "NoiseLock" squelch effectively blocks stray RF.

◆Super Wide Frequency Range:UHF554-963MHz operating frequency range, with AFS "Auto Frequency selection”function, dual-channel receiving, frequency-selective greater.

◆Universal Property:134 MHz transmitter, the four transmitters with different frequencies band, convenient for adjustment and management in KTV.

◆Stable Signal:The system is controlled by microcomputer to find noninterference frequency , making the whole system more stable.

◆LCD Display:Bright and easy-to-read LCD display shows RF/AF signal strengths.channel, frequency, and other working status.

◆Energy Conservation:Accurate low consumption current design, battery life is twice as common one.
